The thing is that soil used for grazing cattle can’t be used for planting vegetables efficiently.
There is a reason why we have different farming, because of different soil quality.
So the effect would be to reduce the area of where we can produce food.
And if you would remove cattle you no longer have natural fertilizer. Mineral fertilizer has a big environmental impact on ground water.
- MaxBarraclough 6y ago> The thing is that soil used for grazing cattle can’t be used for planting vegetables efficiently. This is true, but it's not how modern meat is produced. A lot of high-quality land is used to produce meat that could be used to produce vegan food, no?
- fetbaffe 6y agoI wouldn't be surprised, but do you have any statistics?
- 3131s 6y agoWhat you are missing is that a lot of land is used to grow feed for animals too. Grazing systems supply about 9 percent of the world's production of beef, the rest are crop fed in addition!

Not planting vegetables efficiently != not planting them at all, right? Could the lower yield on such fields still come ahead of lower energy efficiency of meat (in terms of energy expended per calorie of final human food produced)? > So the effect would be to reduce the area of where we can produce food. Surely we can grow something human-edible there. Or could perhaps this land become earmarked for construction, while equivalent amount of very fertile land could be switched from construction to farming? AFAIK there's plenty of settlements built on land that would be better used for farming. > And if you would remove cattle you no longer have natural fertilizer. Is industrialized agriculture even using natural fertilizer? I was under impression modern fertilizers are made in chemical plants and their production doesn't involve animal excrement.
- fetbaffe 6y agoIf it is not efficient it will cost more than it yields, a loss. According to FAO 70% of worlds land surface is not suitable for planting crops. Cattle can transform grass, that we can't eat, to protein that we need. It is actually a good thing, especially if you can't grow anything there. In Sweden we have something called ecological farming, it is certification, to be approved for ecological farming you can't use mineral fertilizers anywhere in your food production. Ecological products are usually somewhat more expensive in the store. Now there are of course lots of farms that is not classified as ecological and they can use mineral fertilizers or natural fertilizers. About a third of all fertilizers for farming used in Sweden is natural.
- TeMPOraL 6y agoThank you for the answers! > If it is not efficient it will cost more than it yields, a loss. I was thinking about less efficient, but still profitable. I presume it's not a binary, and farms aren't operating barely above EROI of 1. > According to FAO 70% of worlds land surface is not suitable for planting crops. That's... super surprising to me. I would have expected something closer to 50-40%. Perhaps it hinges on the definition of "suitability"? I'll look into those stats. > About a third of all fertilizers for farming used in Sweden is natural. That's also surprising to me. Is this number so large because there are so many ecological farms in Sweden, or natural fertilizer is just so popular?
- fetbaffe 6y agoSure, it is perhaps possible for planting crops in areas that is less suitable, I guess that the current economic system we have in the West makes that not feasible. That is why I'm in favor of tariffs on imported goods. With more being produced within your country you can legislate higher requirements on production methods. And when food becomes more expensive to buy, the incentive to have high quality production increases. In the west we no longer have the problem of food shortage, thus we can afford somewhat higher food prices. And of course if you produce more within your country, you can get better salaries. Why Sweden uses that much natural fertilizer I can't really tell. But I found something about high prices on synthetic (mineral or others like natural gas) fertilizers. This was something that started happening globally around 2008. Between September 2007 and September 2008 prices increased with 80 percent globally.

- Agathos 6y agoYou really think your restaurant and supermarket beef is coming from grazing? Those cattle live in dense feedlots, where they are fed corn and soy.
- fetbaffe 6y agoWhere I live (Sweden), yes actually, but I do understand that US are somewhat crazy. Isn't corn production massively subsidized in the US? So it becomes cheaper to feed cattle with corn instead of grazing. Madness. That type of meat production is not something I support.
- Agathos 6y agoDid some googling. The US is the #2 beef exporter, and Sweden is not in the top 15. Admittedly that doesn't necessarily tell me about domestic consumption. http://www.worldstopexports.com/top-beef-exporting-countries/ http://www.worldstopexports.com/top-beef-exporting-countries... Interestingly, the #1 exporter, Australia, has historically used a mix of grazing and feed grains. But they're expecting to grow more feed grains because grazing suffers during droughts, which are increasingly common. Apparently those grains are wheat and barley; corn is definitely an American obsession. I assume that will be grown on land that could otherwise be used to grow food for humans. https://www.beefcentral.com/lotfeeding/grain-sector-faces-new-opportunities-challenges-on-the-way-to-2030/ https://www.beefcentral.com/lotfeeding/grain-sector-faces-ne...
